impacts of two rehabilitation programs on chronic peripheral facial paresis

Conditions: Facial Palsy; Self-rehabilitation; Quality of Life; Motor Recovery

Summary: introduction: peripheral facial paresis (pfp) is a very common disease of various etiologies affecting average adults with no predominance of sex. in 70% of cases, motor recovery is rapid and complete, but in 30% of early pfp, motor symptoms such as paresis and/or abnormal movements (synkinesis, contractures and/or spasms) can live on and jeopardize patients quality of life at medium and even long term. concerning therapeutic interventions, the rehabilitation patient care of pfp is often restricted to the early stage. a recent randomized controlled study showed that early rehabilitation had a positive impact on motor recovery, specifically in severe motor grades, and could also accelerate time of recovery without exacerbating synkinesis. at chronic stage of the pathology, there is no controlled study testing the effect of motor rehabilitation when deficiencies are often considered as fitted and permanents. objective: it is well known in other domains that intensive motor strengthening increases cerebral plasticity in general, and particularly that of sensorimotor command. the main hypothesis of the study is that motor strengthening even at chronic stage of pfp could increase motor function and decrease abnormal motor movements through a self-rehabilitation motor program. the main objective is thus to compare the clinical, kinematic and quality-of-life related impacts of two different rehabilitation programs on motor recovery in unilateral pfp at chronic stage (i.e. at least 1 year after injury): a self-rehabilitation program guided by physical medicine and rehabilitation (pmr) therapist versus facial rehabilitation involving physiotherapist or speech therapist specialized in facial rehabilitation. the main evaluation criterion is the evolution of the sunnybrook facial grading scale composite score between day0 (before rehabilitation) and day180 (after 6 months of facial rehabilitation). method: national, randomized simple blind controlled study, in two parallel groups: both program have to be realized daily for 6 months (day1 to day180). the population is made of adults with unilateral pfp at chronic stage i.e. at least 1 year from injury. evaluations and follow-up of patients will be accomplished in a single center: service de rééducation neurolocomotrice de l'hôpital mondor in créteil (france).
